As the night deepened, Erhu panted and held a strange-looking utensil in his right hand, but in his left hand he carried a few wooden planks and large bags and small bags, and gently knocked on the door of Xie Xiuqi's small courtyard.

After a while, I only heard a sound of footsteps in the courtyard from far and near, the door creaked open, and a small head had poked out, but it was An Xuan.

"How fast? The young master said that you may only be able to customize this item today, and you will only be able to get it back tomorrow at the earliest. ”

Seeing that it was the second tiger, An Qian looked at the strange instrument in his hand curiously, his expression was full of surprise, and he stretched out his hand to bring something for the second tiger, so he asked.

Erhu smiled and handed a lightweight bag in his hand to An Xian, who reached out to help: "Although the things painted by the young master are novel, somehow, they can find similar substitutes, just like the bearings in the middle. ”

Erhu shook the utensils in his hand: "When I asked in the Zhou family's craftsman's shop, Master Zhou said that it could be replaced by the ball carriage axle created by His Royal Highness the ancestor back then. ”

Immediately, he proudly shook the little girl's face full of novelty: "What is it like this rocker arm and what the young master said...... Transmission gear structure. Some of the parts are similar to the booms used in the docks. ”

As the second tiger spoke, his face became a little mysterious, only to see him sneakily close the courtyard door and approach An Qian, and said as he walked inside: "An Qi, have you found it?" I suddenly felt that the young master who was drunk and alive was as smart as His Royal Highness the Ancestor back then-"

"Don't you know, when I showed the three views drawn by the young master to those craftsmen, good guys, those craftsmen were clamoring to buy this mapping method, do you know how much they are willing to give the most?"

He was full of mysteries.

An Qian shook her head suddenly.

Erhu triumphantly drew four fingers: "This number!" And guess how much? ”

"Siwen? Four money? An Qian guessed.

Erhu had a disdainful look on his face: "Guess again?" ”

"Could it be four taels?" An Xuan's face was full of surprise.

The second tiger raised his head to the sky: "Do you still guess?" ”

An Qi's expression was a little helpless, she seemed to know the bad temperament of the second tiger who liked to sell guanzi, but she rolled her eyes and said angrily: "It's not forty taels?" ”

"Exactly! Moreover...... Or gold! Forty gold! Erhu dragged out his voice and said triumphantly.

"Oh my God!" The little girl was stunned and said, "That's enough for the young master to use the wine and food of the previous year...... Just a few strokes that he drew casually? ”

"That's nature." Erhu had a look of pride on his face: "But I didn't sell it, this is the young master's thing, it's good if I can give them a look, if you want to buy it, they have to talk to my young master." I don't think they dare to study it privately, that's against the law. ”

Erhu said proudly.

"They also said that the method of drawing this map is a precedent, and it can definitely be patented at the Imperial Royal Academy of Sciences."

After thinking about it, he added.

"Scared!" The little girl suddenly gasped again: "Wang Academy of Sciences? Parallel with the Tai Academy of Confucianism, one of the two academic meccas of the empire, the Royal Academy of Sciences? ”

She muttered with starry eyes.

Erhu was also full of fascination: "Yes...... That's why I said that after the young master changed, he seemed to be as smart as His Royal Highness the Ancestor back then - His Royal Highness the Ancestor had countless scientific inventions back then, and the young master today is not just like he was back then? ”

An Qian suddenly chuckled: "His Royal Highness the Ancestor has been so smart since he was a child, but the young master of our family seems to have changed after he died drunk...... And His Royal Highness the Ancestor King is the messenger of heaven, and God is an all-round talent. Is its ability limited to scientific inventions? If you want me to say, as long as our young master has His Royal Highness the Ancestral King, I will be satisfied. ”

"That's ...... too" Erhu nodded thoughtfully: "By the way, what about the young master?" ”

"Stay in the study." An Qian didn't know what she remembered, and her expression suddenly became a little gloomy.

I don't know if the young master can think of a good way...... However, such a big matter of the Erhu family, wasn't it solved by him lightly?

The young master is the smartest now, En...... Smarter than Miss. Although the young lady also thought that the fire was different, she couldn't find a way. But didn't the young master just think about it casually, draw a few drawings by hand, and find a way? Even those pictures can be sold for forty gold, and they can apply for a patent at the Royal Academy of Sciences!

Well, the young master will definitely be able to think of a good way!

The little girl, who already had some blind worship for her young master, muttered silently in her heart, and her expression became happy again.

"After I went home and had dinner, I was in a daze in the study, and I didn't drink any more wine. But I kept saying something in my mouth, and I don't know what the hell I'm thinking. ”

"The young master has changed, but he has become a strange ......"

In the end, her heart was full of longing, but she muttered disdainfully.

"Do you like it or don't you like it?" Seeing this, Erhu immediately smiled.

"That's a joy - hey! Erhu, do you have itchy skin? The little girl replied without thinking, but after a while, her face was ashamed.

Then, I saw that she thought about it, and even threatened Erhu angrily: "The young master may have forgotten, but don't think that I don't know why you asked the young master to spare the Qian family in the afternoon, be careful I tell the young master!" ”

Although the words were full of eloquence, the little girl's eyebrows were full of joy, and Ru Yuxiu's face was even more faintly flushed, and she couldn't hide it.

Erhu smiled innocently: "I'm not afraid of what you say, that's just my own thinking, I can't do it really, how can the Qian family take a fancy to me...... And not to mention that the young master already knew, even if he forgot, with the young master's current cleverness, I'm afraid he would have guessed it again when he was at my house in the afternoon......"

As he spoke, he also saw that An Qian was even more angry, so he closed his mouth with a look of horizontal eyebrows and vertical eyes, and only walked with An Qian to the study where the lights were on.

Xie Xiuqi was in a daze in the study.

Although he seemed to have found a way to restrain Tang County's order, and as long as the experiment was successful, everything could be reversed, but at this time, he seemed to have a faint uneasiness in his heart, and he always felt that there was something hidden in this matter that he hadn't noticed-what was going on in the Fang family? If the Tang County Order is countered, can the Fang family really obey their orders?

I guess so...... Uncle Lu and Tang County Ling put pressure together, even if the Fang family has Yongfu to rely on, but offending the two giants in the county is only for his sister's beauty...... Is it really that the Fang family is a brainless person who wants beauties and doesn't want the country?

But why do I feel uneasy in my heart......

He was thinking about it in his heart, but saw that the door was pushed open, and behind An Qi, Erhu was carrying a machine and staggering in.

Xie Xiuqi suddenly woke up from the fugue world: "Second Tiger, are you here?" Ah, it's done so quickly? ”

He didn't have time to take care of the little unfounded uneasiness in his heart, and he was already surprised.

"Yes, young master." Erhu carefully placed the utensils in his hand in front of him and replied respectfully.

"So fast?" Xie Xiuqi walked over happily, carefully examined the utensils, and gradually, nodded with satisfaction: "It's really done." ”

"I thought it would be tomorrow before I could experiment, but now it seems that I have bought some more time - Erhu, you did a good job! Let's get moving. ”

He rubbed his hands together with joy and said in a deep voice.

A few minutes later, two roaring fires had been lit in Xie Xiuqi's small courtyard, Xie Xiuqi squatted by the fire and was silent, but An Qian and Erhu were also full of curiosity.

"What is this doing, young master?" After a long time, the second tiger finally couldn't hold back his curiosity, but whispered to An Xuan.

An Qian spread her hands at Erhu with a puzzled look on her face.

Xie Xiuqi looked at them sideways: "It's a simulated fire scene." You see, these two piles of planks are quite old planks from Fangjia Shipyard, one pile is splashed with oil, and the other pile is not splashed. The oil is exactly the same as the oil I used when I set it on fire. After these two piles of planks are burned out, I will be able to compare them with the things that the two tigers have just prepared, and prove whether my method will work. ”

He explained softly, a smile on his face.

"You don't understand the specific principle, and I won't be able to explain it for a while. There are still some things to think about, and I don't have time to talk about them. All you need to know is that if the experiment is successful, I will have another way of telling if the fire has been poured oil and where it has been poured - even if it is free of impurities. ”

Erhu and An Qian were suddenly full of joy.

Xie Xiuqi looked at the raging fire, but frowned again: "It's just that I have ...... in my heart I seem to be uneasy, and I don't know why. ”

He muttered half-questioningly and half-to himself: "If the experiment is successful, the Tang County Order is no longer a threat, but we will use this to coerce us, and in turn help us put pressure on the other party." ”

"And this Fang family ...... Now it seems that they have a good grasp of it. The victims are them, and it is also our Lu Mansion that proposed a peace treaty and let them hide from each other, and now it has come to this...... And with the Yongfu here, their reliance is extremely sufficient, even if Uncle Lu and Tang County Ling exert pressure together, if the Fang family is iron-hearted, I am afraid they will be able to resist it......"

"So, now it's up to them to see if they have that motive...... Businessmen pursue profits, if there is no huge profit, just a beauty, the Fang family may not risk offending the two giants in the county...... Probably they wouldn't be so unwise......"

The young man muttered vigorously, but he didn't want the two of them to listen to his analysis, and their faces gradually changed.

By the end, Erhu's face was even more pale.

In the end, he was already muttering, "Young master, the villain thinks it...... Most of them will......"
